title: Evaluation of patency of arteriovenous fistula and its relative complications in diabetic patients.
abstract: OBJECTIVE
  To study the arteriovenous fistula patency, duration of its maintenance, and its relative complications.
  
  
  METHODS
  One hundred and thirty patients who had undergone hemodialysis during five years (1996 to 2001) were included in this study. The patency rate and complications, including paresthesia, pain induced by ischemia, venous hypertension, infection, erythema, and edema, were assessed. Data were recorded in the pre-designed questionnaire and statistically analyzed using t test.
  
  
  RESULTS
  Mean ± standard deviation age of the patients was 58.08 ± 11.73 years (range, 18 to 80 years). Most of the fistulas were created at the left bracheocephalic (58 subjects). Side-to-side technique was the mostly applied technique (99.2%). The fistula patency was 100%, 92.64%, 89.48%, 84.38%, and 83.61% at year 1 to 5, respectively. There was a significant negative correlation between the subjects' age and maintained patency (P = .02). However, no significant difference was observed between the maintained patency and other variables, including gender, location of the fistula, and the type of the technique applied for creation of the fistula (P > .05).
  
  
  CONCLUSIONS
  Diabetes does not have a negative impact on the rate of patency and its duration in arteriovenous fistula. However, further investigations on a larger population are recommended.
